Lens Description

The Sigma 17-70mm F2.8-4 DC Macro OS HSM is a wide to short telephoto zoom designed for cameras with a APS-C (1.5X) sensor. This bright variable-aperture zoom covers a 17mm to 70mm focal-range. It provides the same field of view as a 25.5-105mm lens on a Full-Frame camera. An optical Image Stabilization System built into this lens compensates for camera shake.

This zoom can focus down to 22cm from the imaging plane which gives it a maximum magnification of 0.37X. The lens supports autofocus and features a switch to disengage AF for focusing manually. A Super-Sonic motor inside the lens delivers very fast and relatively quiet AF.

This version has a Sony A lens mount. Follow this link for all current compatible digital cameras: Sony A mount cameras with APS-C (1.5X) sensors. Sigma also made this lens available for Canon EF, Nikon F, Pentax K, Sigma S mounts.
